Topic: IDLE Time for Java Application not SYSTEM Idle Hi I am Krishna , I want to calculate idle time for an application.That is , if user1 uses the application for example called "yahoo site" for checking mails , then after 10 mins he went to outside , from 11th min the status of application should show (Like Yahoo messenger after certail time it shows idle time ) in another ADMINJSP page for Admins that how much this user1 idle say.. : 1 min idle 2 min idle .... .... 10 min idle Now user1 comes and now clicks on application . then ADMINJSP page should show total IDLE time (10 mins idle). And he again after 15 mins he went some where from 16th min the status of the application should show in ADMINJSP page.If user1 left the application like that then the application should be idle for 1 hour i.e 1 min idle 2 min idle ... ... 59 mins idle 60 mins idle Time Up -- Session Expired then he has to login again. So the above is the issue --------------------------------------------------------------------------- What i have done ..................issssssssssssss ------------------------------------------------------------------------- I have taken time for last request by using getLastAccessedTime() I have taken present time System.currentTimeMills() Taking the difference we will get the idle time . But the problem here is When user1 click on any page only this calcuting will be done and showing to ADMINJSP because getLastAccessedTime works only when any requests comes , but we dont want like that , we want the application without any requests from user1 the application should show idle for 1 min , 2 mins , 3 mins...so on upto user1 uses the application then the time should be normal. I have also tried all the EVENTS classes in HttpSessionBinding like valueunbound()...or sessiondestroy() etc. Can any one please help me by giving any CODE.If you need more information plz ask me Plz plz plz plz this is very urgent plz can any please send me the CODE , ihave tried this very hard but no idea how to do? long startTime = session.getLastAccessedTime(); long stopTime = System.currentTimeMillis(); long diffTimeInSecs = (stopTime - startTime) / 1000 ; gives idle time for every request Regards Krishna
